There are many mosquitoes in summer, but there are few when swallows nest. This is because swallows feed on mosquitoes, and swallows that eat pests become human-friendly animals. Therefore, the arrival of swallows will reduce the intrusion of mosquitoes on people, not only reduce the number of people bitten by mosquitoes, but also protect crops, so swallows are a kind of beneficial birds.

Swallows are also a barometer of the weather. We all studied the text in primary school. Swallows flying low means it may rain heavily. This is because there was more water in the air before the heavy rain. So some small mosquitoes can't fly high when their wings get wet. Swallows can fly very low because they want to prey on mosquitoes. In addition, with the increase of air pressure, it is more difficult for swallows to fly higher and higher. Therefore, people knew it was going to rain when they saw the swallows flying low.
